Denial - Caused By Right-brain Deficit Disorder

Left brain good, right brain bad? I’m not so sure . . . | The Times

In his recent book The Master and his Emissary, the neurologist, psychiatrist and philosopher Iain McGilchrist highlights some intriguing differences between the right and left hemispheres of the brain when it comes to certainty. The left-brain, it seems, demands it. Only the right-brain is adept at holding several ambiguous possibilities in suspension. So far, so good. ...Straight answers to questions are, after all, no bad thing.
Or are they? There is a dark side to this drive for certainty. Unchecked, the left-brain rejects information that doesn’t fit with its accepted theory, is an expert at denial and has a penchant for delusional optimism....
Nuanced understanding and a circumspect position are signs of weakness. Take the “uncertainty” and “unprovenness” that climate sceptics assure us exists around climate science. No matter how patiently scientists talk of overwhelming likelihoods and near-total consensus, there’s a lingering sense that the sceptic has still won the argument....
Unreasonable demands for certainty are met with bogus claims of it.
While happily disregarding inconvenient evidence, the left-brain not only shows exaggerated optimism about outcomes but also about its own ability....
Let’s suppose that today we are facing a set of unprecedented challenges. Reaching for the same old solutions won’t help; nor will denial....
If it is true that these challenges require new thinking, it could be that a move away from our sinister obsession with certainty is important. Of course decisions still need to be made, but it’s legitimate to make the best judgment on the evidence and the understanding that we have.

So demanding boring old evidence is a left brain problem, but so it seems is Alarmism...

One researcher studying head injuries writes: “Children with right-brain deficit disorder ignore task obstacles, accept impossible challenges, make grossly inadequate efforts and are stunned by the poor outcomes.”
The left-brain is dogmatic, preferring to rely on theory rather than evidence. Researchers experimenting on split-brain sufferers showed them a series of lights, mainly green and occasionally red; the patients had to predict what came next. Those with access only to the right-brain adopted the most successful strategy of picking green every time; those stuck with the left developed complex theories and insisted upon their merit, despite much lower success. When the researchers then rigged the experiment, so that the guesses all turned out to be correct, the right-brainers admitted to doing nothing differently, but the left-brainers assured the researchers there was a pattern and they had finally cracked it.
Patients with right-brain injuries will make up convincing answers to questions, rather than admitting they do not know, and show what the California-based neuroscientist V. S. Ramachandran calls “an unbridled willingness to accept absurd ideas”. The left-brain prefers theory to observation, and prefers what it already knows


Left brain prone to failure through confirmation bias and right brain prone to success through trial and error?

So everyone who believes anything is brain damaged- do the authors of this report actually believe what they say?
